quick_answer: Quick answer: You cannot drive through San Francisco on a freeway, because there isn't one. Interstate 80 ends in San Francisco — California statute puts its western terminus at US-101 near Division Street — and US-101 leaves the freeway inside the city and becomes Van Ness Avenue, a signalized surface street. So the real decision is which way to go around. If you must cross the city, do it outside the afternoon: Caltrans District 4's own data shows 15 of the Bay Area's 20 worst bottlenecks are PM peak, with Thursday the most congested day. BoardSpy checks your route before you leave and tells you when to go.

  What is the best time to drive through San Francisco?,Morning rather than afternoon, and early in the week. Caltrans District 4's calendar-2024 data shows 15 of the Bay Area's 20 worst bottlenecks occur in the PM peak and only 5 in the AM, with the PM peak accounting for 59% of daily lost lane-mile hours. The most congested days in order are Thursday, Wednesday, Tuesday and Friday.
  Is there a freeway through San Francisco?,No. Interstate 80 ends in San Francisco — California statute defines its western terminus at US-101 near Division Street — and US-101 leaves the freeway inside the city at Mission Street and continues as Van Ness Avenue, a signalized surface street. The Embarcadero Freeway and much of the Central Freeway were demolished after the 1989 Loma Prieta earthquake and replaced with boulevards rather than freeways. I-280 is not a bypass either: it ends at an at-grade intersection at King and 5th Streets.
  How do I bypass San Francisco entirely?,Take the East Bay. From US-101 or I-880 north, join I-80, then at the Hoffman Split in Albany follow I-580 across the Richmond–San Rafael Bridge, which lands on US-101 in San Rafael about ten miles north of the city. I-580 never enters San Francisco. The toll is $8.50 westbound. Note that the I-580/US-101 interchange in San Rafael is incomplete — some movements route via Sir Francis Drake Boulevard.
  How much are the Bay Area bridge tolls?,All seven state-owned bridges charge a flat $8.50 for a two-axle vehicle as of 1 January 2026, with no cash accepted anywhere. The Golden Gate charges $10.25 with FasTrak, $10.50 by licence plate and $11.25 by invoice as of 1 July 2026, southbound only. Rates rise 50¢ a year through 2030, and from January 2027 the payment tiers split, so check before you travel.
  Does the Bay Bridge have congestion pricing?,Not any more. The time-of-day toll tiers were suspended in April 2020 and have not returned — the toll is a flat $8.50 at every hour of every day, for every payment method. The only time-based rate on the state bridges is the carpool discount of $4.25, weekdays 5–10 a.m. and 3–7 p.m., which from January 2026 requires three occupants at all seven bridges.
  Is San Francisco traffic as bad as Los Angeles?,No, and the data is emphatic. ATRI's 2026 Top 100 Truck Bottlenecks has zero San Francisco entries, and only one of Caltrans District 4's twenty worst Bay Area bottlenecks is in San Francisco County. INRIX puts San Francisco at exactly the US average of 49 hours lost per driver, against 87 for Los Angeles. The difficulty of driving through San Francisco is a routing problem rather than a congestion problem.
